miniz_oxide

Pure rust replacement for the miniz deflate/zlib encoder/decoder using no unsafe code. Builds in no_std mode, though requires the use of alloc and collections crates.

This project is organized into a C API shell and a rust crate. The Rust crate is found in the miniz_oxide subdirectory.

miniz_oxide 0.7.x requires at least Rust 1.50.0 Older versions 0.5.x and 0.6.x require at least rust 1.40.0, 0.3.x requires at least rust 0.36.0.

For a friendlier streaming API using readers and writers, flate2 can be used, which can use miniz_oxide as a rust-only back-end.

miniz_oxide_C_API

The C API is intended to replicate the API exported from miniz, and in turn also part of zlib. The C header is generated using cbindgen. The current implementation has not seen a lot of testing outside of automated tests, is a bit weak in documentation and should be seen as experimental.

The data structures do not share the exact same layout that is specified in miniz.h (from the original miniz), and should thus be allocated via the included functions.

TODO

Testing

$ cargo test
$ ./test.sh

Benches

$ cargo bench --features=benching

or to compare to miniz

$ ./travis-after-success.sh

Including in C/C++ projects

Link against the libminiz_oxide_c_api.a generated by build.sh. The generated header that can be used is miniz.h (using the original miniz headers may or may not work), which currently also uses miniz_extra_defs.h for some static definitions.
